cce57de0f4 fix: Address code review issues from gist analysis
## Fixes Applied

### 1. Fabricated Benchmarks
- Rewrote docs/benchmarks/BENCHMARK_COMPARISON.md - removed false "100-4,400x faster" claims
- Fixed benchmarks/graph/src/comparison-runner.ts - removed hardcoded latency multipliers
- Fixed benchmarks/src/results-analyzer.ts - removed simulated histogram data

### 2. Fake Text Embeddings
- Added prominent warnings to agenticdb.rs about hash-based placeholder
- Added compile-time deprecation warning in lib.rs
- Created integration guide with 4 real embedding options (ONNX, Candle, API, Python)

### 3. Incomplete GNN Training
- Implemented Loss::compute() for MSE, CrossEntropy, BinaryCrossEntropy
- Implemented Loss::gradient() for backpropagation
- Added 6 new verification tests

### 4. Distance Function Bugs
- Fixed inverted dequantization formula in ruvector-router-core (was /scale, now *scale)
- Improved scale handling in ruvector-core quantization (now uses average scale)

### 5. Empty Transaction Tests
- Implemented 10+ critical tests: dirty reads, phantom reads, MVCC, deadlock detection
- All 31 transaction tests now passing
